The site of the new Hospital for Sick Children research tower in downtown Toronto was a hive of activity Oct. 21 as concrete was poured for the building’s “mat” foundation.

A total of 1,600 cubic metres of concrete were poured continuously over a 12-hour period. Sitting on top of 20 caissons, the foundation is 35.75 metres long, 14.7 metres wide and 2.5 metres high.

General contractor EllisDon supervised the pour. Ready-mixed concrete supplier St. Marys CBM mobilized three Toronto-area plants. The 750,000-square-foot facility was designed by Diamond + Schmitt Architects with HDR Inc. The team includes structural engineers Halcrow Yolles and mechanical-electrical engineers H.H. Angus & Associates Ltd. The 21-storey research and learning tower will be the largest such high-rise facility in Canada. Completion is scheduled for 2013.
